The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

As shown in fig. 2, an embodiment of the present invention provides an information indication method, including:

step 201: and the network side equipment configures a first transmission resource, wherein the first transmission resource is a transmission resource corresponding to the reference signal.

The network side device may specifically be a base station. The Reference Signal may include at least one of a channel state information Reference Signal (CSI-RS) and a Tracking Reference Signal (TRS).

Step 202: the network side equipment sends a first signaling, wherein the first signaling is used for indicating resource information on a first transmission resource, the first signaling comprises at least one of a high layer signaling and a layer 1 signaling, and the resource information comprises at least one of the following items:

whether the reference signal is present;

whether there is an update of the reference signal.

In this step, for an idle or inactive terminal, the high layer signaling mainly includes System Information (SI), master Information Block (MIB) and/or System Information Block (SIB). The layer 1 signaling may include a Paging Early Indication (PEI) and/or Downlink Control Information (DCI).

In the embodiment of the invention, the network side equipment configures the transmission resource corresponding to the reference signal, and indicates the resource information on the first transmission resource through the first signaling, if the reference signal exists, whether the reference signal exists or not, and the like, so that the terminal in an idle state or an inactive state can accurately acquire the resource information on the first transmission resource, the blind detection operation of the reference signal by the terminal can be effectively avoided, and the power consumption of the terminal is further reduced.

wherein the signaling type comprises at least one of:

high-level signaling;

layer 1 signaling.

Here, the higher layer signaling carrying the indication information is system information, and the system information includes at least one of the following:

a master information block MIB;

a system information block SIB1;

a SIB for configuring the first transmission resource.

As a first optional implementation manner, in a case that the first indication information is first preset information, the first indication information is used to indicate that a signaling type corresponding to the first signaling is a high layer signaling or is used to indicate that a layer 1 signaling is deactivated;

For example, the base station instructs the terminal to determine resource information on the first transmission resource according to SIB or L1 using SI display. Preferably, the SI is an SIB configured with reference signal resources, where the SIB carries a 1-bit indication, such as L1 otherwise signaling trs, and when L1 otherwise signaling trs =1, the terminal is instructed to determine resource information on the first transmission resource by using L1 signaling, which may also be described as activating L1 signaling, where the L1 signaling may be carried by using a downlink control channel, for example, the L1 signaling is reserved bits of a paging DCI (paging DCI reserved bits) or a PEI based on the DCI or a PEI based on a sequence; when L1 orsibitionanottrs =0, the terminal is instructed to determine the resource information on the first transmission resource by using an SIB, which may also be described as deactivating layer 1 signaling, where the resource information on the first transmission resource may be determined according to whether the SIB configuring the reference signal exists in the system information received by the UE, and if the SIB does not exist, it indicates that the reference signal does not exist on the first transmission resource, and if the SIB exists, it indicates that the reference signal exists on the first transmission resource.

As a second optional implementation manner, the first indication information includes N bits, where N is greater than or equal to 2;

In this implementation, the network side device indicates resource information on the first transmission resource by at least 2 bits, for example, 2 bits are used for indication, L1 indicating trs =01 indicates that a paging DCI is used to indicate whether a reference signal is updated, and L1 indicating trs =11 indicates whether a reference signal is updated or not by using PEI; l1 indicative trs =11 indicates that no L1 signaling is used to indicate whether the reference signal is updated (not using L1 signaling is equivalent to using SIB to indicate whether the reference signal is updated).

In an embodiment of the invention, the first reference information may specifically be a reference signal validity timer (reference signal validity timer), and when the SIB carries the reference signal validity timer, implicitly indicates to determine the resource information on the first transmission resource by using L1 signaling, otherwise, determines the resource information on the first transmission resource by using the SIB. The reference signal validation timer is configured by the SI, and is configured to indicate that, after the UE acquires the indication of the existence of the reference signal according to the L1 signaling, particularly after obtaining the deterministic indication of the existence of the reference signal on the first transmission resource, the deterministic indication continues to exist for a time corresponding to the subsequent reference signal validation timer.

In another embodiment of the present invention, except for configuring a reference signal validation timer in an SIB, the base station and the terminal may also agree in advance a preset threshold Th1, and when a value Th1 corresponding to the reference signal validation timer is greater than or equal to Th1, the base station implicitly indicates that the terminal needs to determine resource information on the first transmission resource according to the SIB, otherwise, the terminal needs to determine the resource information on the first transmission resource according to layer 1 signaling. Preferably, the preset threshold corresponds to a correction period of the system information.

In the embodiment of the invention, in a scene that the reference signal resource configured for the connected UE changes frequently, the base station can configure the L1 signaling for indicating the existence or the update of the corresponding reference signal, so that the power consumption increase caused by that the UE reads SIB messages frequently can be avoided; in a scene that a reference signal resource configured for the connected UE slowly changes, the SIB is configured to indicate the existence or update of a corresponding reference signal, which is beneficial for a base station to avoid sending a reference signal L1indication signaling of always on, thereby reducing the overhead and power consumption of the base station side, and simultaneously avoiding the situation that the terminal cannot timely obtain the reference signal actually being transmitted due to error detection of the L1 signaling or untimely sending of the signaling, thereby increasing the power consumption of the UE side.

Of course, similarly, the base station may also determine, by using the higher layer signaling, the resource information on the first transmission resource configured by the higher layer signaling according to the PEI signaling or the L1 signaling, so as to avoid that the higher layer signaling and the higher layer signaling repeatedly indicate the resource information.

configuring a search space corresponding to a first SIB and a monitoring period of the search space through system information SI, wherein the monitoring period comprises an actual monitoring period, and the first SIB is an SIB except SIB1.

Further optionally, configuring a listening period of the search space through system information SI, including:

configuring the actual listening period through a first SIB.

Optionally, the listening period further includes a nominal listening period, and configuring the nominal listening period through the system information SI includes: configuring the nominal listening period through SIB1.

Here, the base station indicates the above resource information through the SI, and the terminal may obtain a semi-static resource information updating method according to an indication of a paging DCI system information update (paging DCI SI update) bit. Alternatively, the base station may also adopt a faster updating method, in which the updating speed is intermediate between the system information and the L1 signaling. The behavior of the base station and the terminal is as follows:

base station behavior: the base station transmits a corresponding search space (search space) through SI, for example, SIB1 configuration SIB-X (SIBs other than SIB1, such as SIB2, SIB3, etc.), and a nominal listening period T and an actual listening period (or parameters related to the actual listening period) of the search space; more specifically, when the higher layer signaling configures the search space, it is necessary to configure a monitoring period T according to the existing protocol, and if the system message changes or the terminal just accesses the cell according to the prior art, it is necessary to monitor the PDCCH according to the period T to obtain the scheduling information of the SIB-X; the actual listening period related parameters may also be a function of the DRX cycle, for example, the actual listening period is N x DRX cycle, so that the behavior of the UE is clearly different from the prior art.

UE behavior: if the paging DCI system information update bit (paging DCI system information update bit) does not trigger system information update, the UE monitors the search space corresponding to SIB-X periodically according to an actual monitoring period configured by the base station, for example, N × T is a search space monitoring period configured by SI; or performing PDCCH monitoring corresponding to SIB-X once or multiple times every N × DRX cycle, where multiple times may be that the terminal performs PDCCH monitoring on all search spaces configured by the base station in the DRX cycle that needs to be monitored, and one time of PDCCH monitoring may be that one search space is monitored by using the DRX cycle with the PDCCH monitoring cycle granularity being N × DRX cycle. Optionally, if the paging DCI system information bits update triggers system information update, but the UE still monitors the search space corresponding to the SIB-X according to the actual monitoring period configured by the base station in the current system information update period, for example, monitors the search space corresponding to the SIB-X with N × T as the period.

Because idle/inactive UE which has finished cell selection in the prior art can receive updated system messages in the next SI modification period only when a paging DCI SI update field informs a terminal to receive SI after SI reception is finished, the granularity of updating the system messages is the SI modification period, the period can be 2,4,8 or 16 times of DRX period, and the updating speed is slow. In the embodiment of the invention, the terminal monitors the search space corresponding to the SIB-X related to CSI-RS/TRS configuration according to the actual monitoring period configured by the base station, and the SIB-X can be monitored by the terminal according to the actual monitoring period configured by the base station without triggering the system message update by the paging DCI system information bit update first or whether the paging DCI system information bit update triggers the system message update or not, so that compared with the existing SI update mechanism, the resource information on the first transmission resource can be obtained more quickly, and the terminal is prevented from frequently decoding SSB and/or SIB1. In addition, since the actual monitoring period size is configurable, for example, the PDCCH is monitored every N DRX cycles, the power consumption of the terminal is controllable.

wherein the SIB is used to indicate resource information on a first transmission resource;

the layer 1 signaling is used to indicate whether the SIB is updated.

Further optionally, the layer 1 signaling carries SIB version information, and the SIB carries SIB version information;

Further optionally, the method according to the embodiment of the present invention further includes:

In the embodiment of the present invention, the resource information on the first transmission resource may be indicated by a higher layer signaling and a layer 1 signaling. The specific base station side behavior and terminal side behavior are as follows:

base station side behavior: the base station indicates a first SIB (SIB-X) to be updated through L1 signaling, such as a paging DCI reserved bits or PEI; more specifically, the L1 signaling may not only indicate the existence of a reference signal configured by a higher layer signaling, but also indicate an update message or a change message of SIB-X, where the SIB-X update message mainly indicates that SIB-X is updated from an old version to a new version, and is not limited to indicating whether the original SIB-X exists. Optionally, the SIB-X update message carried by the L1 signaling may be version information of SIB-X, such as SIB-X _ version _ Index, for example, SIB-X _ version _ Index =0,1,2,3,4; the preferred SIB-X also contains SIB-X version information. The base station indicates the version information of this SIB-X in SIB1. Preferably, the protocol may agree on a maximum number K of SIB-X changes within a system information update period, for example, K = 1or 4, i.e. SIB-X may be updated a maximum of K times within a system message update period. Optionally, the base station may also configure the maximum number of SIB-X changes in one system message update period using the system information.

And (4) terminal behavior: and the terminal reads SIB-X updating or directly deactivates SIB-X according to the indication of the paging DCI reserved bits in the system information updating period of receiving the indication of resource information change. Whether the base station triggers system information updating through a paging DCI system information update bit or not in the current system information updating period or not, and the terminal monitors SIB-X according to the obtained SI configuration to obtain SIB-X updating; or directly deactivate the original SIB-X configuration. Since the SIB-X update indication carried by the L1 signaling may include version information SIB-X _ version _ Index of the SIB-X, and the SIB-X may also include the version information, at this time, if the terminal has received the updated SIB-X, the terminal will not receive the SIB-X of the version again after receiving the SIB-X version information in the L1 signaling; for the UE which just accesses the cell, the SIB-X can be directly received, and whether updating is needed or not can be determined through SIB-X updating indication information in L1 signaling.

Compared with the prior art that the update of the system Message is triggered by the update bit of the system Message carried by the Short Message (Short Message) field in the paging DCI, the method can trigger the update of the SIB-X only by L1 signaling, and thus, the maximum benefit is that the L1 signaling is configured to indicate the resource information on the first transmission resource. For a scenario with frequent reference signal change, if according to the prior art, under the condition that the SIB cannot be updated, such as within one SI modification period, the base station can only indicate that all or a subset of CSI-RS/TRS corresponding to the current CSI-RS/TRS resources of the terminal cannot be adopted by the UE, once the indicated CSI-RS/TRS cannot be adopted, the SIB-X cannot continue to provide the energy saving gain for the UE. The method of the invention not only can indicate the CSI-RS/TRS resources which are configured currently and have no CSI-RS transmission, but also can realize the rapid update of SIB-X, thereby providing more energy-saving gain for UE.

In a first optional implementation manner, the first signaling includes a paging advanced indication PEI and paging downlink control information DCI;

In the implementation mode, the base station configures the PEI in a first period, and then the base station indicates the resource information on the first transmission resource by using the PEI; the base station does not configure a paging DCI reserved bits in a first period to indicate resource information on the first transmission resource; for example, the first period indicates a time when the base station configures the PEI for the terminal, and at this time, the base station does not configure a paging DCI reserved bit for indicating the resource information on the first transmission resource within the time of the first period, and only uses the PEI to indicate the resource information; if the base station does not configure the PEI in the second period, the base station indicates the resource information on the first transmission resource by using the paging DCI reserved bit in the second period, for example, the second period indicates a time period in which the base station does not configure the PEI for the terminal, and at this time, the base station configures the paging DCI reserved bit to indicate the resource information on the first transmission resource.

UE behavior: if the base station is configured with the PEI in the first period, the UE acquires the resource information on the first transmission resource only according to the PEI indication; and if the base station does not configure the PEI in the second period, the UE acquires the resource information on the first transmission resource according to the indication of the paging DCI reserved bit.

The implementation mode can effectively avoid indicating the resource information by using the PEI to the maximum extent, is beneficial to energy conservation of the UE, because the paging DCI is not necessarily sent, and reduces the power consumption of the UE to the maximum extent by using the paging DCI reserved bits when the PEI is not configured.

In a second optional implementation manner, the first signaling includes PEI and paging DCI;

In this implementation, the base station behavior and the terminal behavior are specifically as follows:

base station behavior: the base station configures PEI and paging DCI reserved bits to jointly indicate resource information on first transmission resources, the PEI indicates the resource information on the first transmission resources in a first DRX period, and the paging DCI reserved bits indicates the resource information on the first transmission resources in a second DRX period.

UE behavior: and the UE acquires the resource information on the first transmission resource according to the PEI instruction in the first DRX period, and acquires the resource information on the first transmission resource according to the paging DCI in the second DRX period. For example, the resource information in the first DRX cycle may be different from the resource information in the second DRX cycle, for example, the resource information may have different transmission beams or occupy different bandwidths.

In an optional embodiment of the present invention, the first signaling is layer 1 signaling, and the layer 1 signaling includes PEI and paging DCI;

Optionally, the first resource information is used to indicate whether a reference signal exists, and the second resource information is used to indicate whether a reference signal exists or not.

In an embodiment of the invention, the first resource information is used for indicating whether a reference signal exists, and the second resource information is related information of the reference signal, such as beam information.

The base station behavior and the terminal behavior are specifically as follows:

base station behavior: the base station configures the PEI to indicate, together with the paging DCI, resource information of the first transmission resource, and the PEI indicates the first resource information, e.g., at least 1 bit for indicating presence of a reference signal; specifically, 0 indicates that the corresponding CSI-RS/TRSs of all the CSI-RS resources exist, 1 indicates that only the first configured CSI-RS resource subset exists, 2 indicates that the CSI-RS/TRS exists in the first two CSI-RS resource subsets, and 3 indicates that all the CSI-RS resources do not exist; the Paging DCI reserved bits indicates second resource information, for example, a finer granularity of a reference signal corresponding to one bitmap is configured, for example, each bit of the bitmap corresponds to or is associated with CSI-RS resources of at least 1 beam or 1 CSI-RS resources set. Or the PEI indicates a CSI-RS/TRS resource set corresponding to the first beam set, and the paging DCI reserved bits indicates a CSI-RS/TRS resource set corresponding to the second beam set, wherein the optional CSI-RS/TRS resource set corresponding to the first beam set and the CSI-RS/TRS resource set corresponding to the second beam set are respectively defined in the SIB-X.

UE behavior: the UE obtains first resource information indicated by the existence of the CSI-RS/TRS according to the PEI, and obtains second resource information according to the paging DCI reserved bits. In this way, the terminal is facilitated to reduce the capacity for indicating the existence of the CSI-RS/TRS in the PEI, for example, the type of the indicated existence of the CSI-RS/TRS is reduced for the PEI (sequence based PEI), the size of the corresponding field for indicating the existence of the CSI-RS/TRS is reduced for the DCI based PEI, and the PEI detection performance is facilitated to be improved.

Optionally, the first transmission resource includes M resource groups;

the first resource information is resource information of a first part of the M resource groups, and the second resource information is resource information of a second part of the M resource groups.

In an embodiment of the application, the base station configures PEI and paging DCI to jointly indicate resource information on the first transmission resource, the PEI is configured to indicate resource information of M1 resource groups, and the paging DCI is configured to indicate resource information of M2 resource groups, where M1+ M2= M, the terminal acquires the resource information of the M1 resource groups according to the PEI, and acquires the resource information of the M2 resource groups according to the paging DCI, so that a larger bit number occupied by the resource information on the paging DCI or the PEI can be effectively avoided. Optionally, the first resource information is used to indicate whether a reference signal exists, the second resource information is used to indicate whether an SIB is updated, and the SIB is used to indicate whether the reference signal exists updated;

or, the first resource information is used to indicate whether an SIB is updated, the second resource information is used to indicate whether a reference signal exists, and the SIB is used to indicate whether the reference signal exists for updating.

base station behavior: the base station configures PEI and paging DCI to jointly indicate resource information on the first transmission resource, and the PEI indicates whether a reference signal is updated or not, for example, a bitmap is used to indicate whether CSI-RS/TRS corresponding to the CSI-RS resource is updated or not, and each bit corresponds to different CSI-RS/TRS groups; the Paging DCI reserved bits indicate whether SIB-X is updated or not, and the SIB-X is used for indicating whether a reference signal is updated or not. Or, the PEI is configured to indicate update indication information of the SIB-X, where the SIB-X is configured to indicate whether a reference signal is updated or not, and the paging DCI reserved bits uses a bitmap to indicate whether a CSI-RS/TRS resource corresponds to a CSI-RS/TRS resource, for example, each bit corresponds to a different CSI-RS/TRS group;

UE behavior: and the UE obtains the rapid updating indication of the SIB-X according to the PEI or the paging DCI reserved bits. If the paging DCI indicates that the current SIB-X has been updated, the UE disregards the current PEI indication within the time that the SIB-X update is not obtained.

In an embodiment of the present invention, the first signaling is layer 1 signaling, and the sending, by the network side device, the first signaling includes:

In this embodiment, the base station uses L1 signaling to indicate the resource information on the first transmission resource, and if the base station uses the paging DCI reserved bits to indicate, the base station side does not send the indication that the paging DCI reserved bits is dedicated to the resource information when there is no paging information or a short message is sent. Or, the base station may indicate the resource information using Paging DCI only when there is a page or short message transmission. More specifically, when a Short message indication (Short Messages Indicator) field in the paging DCI is set to a first preset value and/or a Frequency Domain Resource Allocation (FDRA) field is set to a second preset value, the base station side does not send the paging DCI specifically for indicating the resource information. The first preset value is preferably all 0 bits, and the second preset value is preferably all 1 bits or all 0 bits.

Therefore, the UE of the Rel-15 or the Rel-16 cannot be awoken by mistake to receive the paging message due to the sending message of the paging DCReserved bits, and the power saving of the legacy UE is not influenced.

In an embodiment of the present invention, the information indicating method further includes:

In this embodiment, the base station indicates resource information on the first transmission resource by using L1 signaling, and after the resource information indicates that the reference signal does not exist, if the SIB-X (the first SIB mentioned above) is not updated, the reference signal cannot be indicated as existing again by the L1 signaling. The L1 signaling at least comprises paging DCI and PEI.

In this embodiment, the L1 signaling may indicate resource information on the first transmission resource, and may of course allow to be re-indicated as reference signal present after being indicated as absent, but from a higher layer protocol perspective, once the reference signal is indicated as absent, the reference signal corresponding to the SIB-X configuration is changed, and if there is no system information update, it should not be considered that the SIB-X is re-configured.
